Simple method of transscleral fixation of a posterior chamber intraocular lens in the absence of the lens capsule.

Background: There are several advantages to implanting a posterior chamber intraocular lens (IOL) in the ciliary sulcus when the lens capsule is absent. I have developed a simple method of fixating an IOL into the ciliary sulcus which does not require different needles, multiple needle passes, scleral dissection, or awkward surgical maneuvers.

Methods: Thirty eyes were enrolled in this study. All eyes were either aphakic, requiring a secondary lens implantation, or required IOL exchange. The patients were followed for 30 months. Using a single 10-0 double-armed, polypropylene suture, a through-and-through infraciliary scleral pass secured each haptic without tying. The lens was then positioned into the ciliary sulcus and the knots tied outside the eye under direct visualization.

Results: This procedure has been used in 30 eyes without erosion of sutures, dislocation or tilting of the IOL, or induced astigmatism. Twenty-one eyes (70%) had spectacle-corrected visual acuity of 20/40 or better.

Conclusion: The results of this study demonstrate that posterior chamber transscleral fixated IOLs give improved postoperative visual results.
